The grimoire reveals in seductive detail a system of sex magic taught to mankind by Lilith, by which she may be summoned as a lover and teacher. The working journal of the ill-fated German magician who rediscovered this lost necromantic text, and put into practice its obscene rituals, provides terrible evidence that some books are too dangerous to be permitted to exist. Liber Lilith is a powerful and disturbing novel which charts the disintegration of a German occultist, Karl Steiger, who comes across an ancient grimoire which sets out rites by means of which the great demoness Lilith may be called forth. The novel opens with an introduction by the editor of the journal kept by Steiger, and then follows with a reproduction of the grimoire itself. Next comes the working journal of Steiger, and we follow the progress of the ill-fated occultist as he discovers the grimoire, steeps himself in its shadows, and is beguiled by the glamours of Lilith. He is compelled to enact the rites as set out in the grimoire, and he gradually succumbs to madness as Lilith answers his call and he is enmeshed ever deeper in her dark and sinister web.
